Benefits of technology

The patent describes a device and network that can communicate over multiple mediums, such as powerline, telephone line, and coaxial cable. This allows for simultaneous communication using different frequency ranges. The device includes a single reference design with filters and components to connect to different mediums. The network includes a first section of mains cable and a second section of mains cable connected via a junction box, a coaxial cable network, and two devices for transmitting and receiving messages. The technical effects of this invention include improved reliability and flexibility in communication over multiple mediums, as well as better quality of service and cost-effectiveness.

Problems solved by technology

In some cases the phone line or coax in the home may be unused by any apparatus.
These device-to-device wires can become very complex, if, for example, other components such as a stereo system are also connected to the television set.
The use of a dedicated wire between devices additionally limits which devices are able to communicate with one another.
In some PLC systems, it may be difficult to pass communications through the junction box, particularly if they are on different alternating current (AC) phases.

second embodiment

[0082]FIG. 5 is a block diagram of the multi-network interface device 200. In this embodiment, the multi-network interface device 200 is configured to communicate a first signal via the low band 304 over a powerline and to communicate a second signal via the high band 306 over a telephone line. The multi-network interface device 200 additionally comprises a second telephone line interface 208. The second telephone line interface 208 may be used to communicate voice, ADSL, VDSL, or HPNA signals within band 310.

[0083] To allow communication between the telephone line interface 202 and the second telephone line interface 208, an optional second inductive coupler 502 may be placed between the surge protector 402 and the inductive coupler 404. The second inductive coupler 502 is coupled to an optional low pass filter 504 to isolate the signal within the band 310 from other communications signals communicated within the high band 306. The low pass filter 504 may pass frequencies below app...

third embodiment

[0084]FIG. 6 is a block diagram of a multi-network interface device 200. In this embodiment, the multi-network interface device 200 is configured to communicate a first signal via the low band 304 over a powerline, to communicate a second signal via the high band 306 over the powerline, and optionally to communicate the second signal or a third signal via the high band 306 over a telephone line. The multi-network interface device 200 comprises a second telephone interface 208 from which a fourth signal, in band 310, may be communicated as discussed in connection with FIG. 5.

[0085] The multi-network interface device 200 comprises a network processor 412 having a single high frequency AFE 416 configured to receive or transmit signals communicated via the high band 306 over both the powerline and the telephone line. The single high frequency AFE 416 optionally includes passive sharing of the powerline and the phone line. As such, the single high frequency AFE 416 can only receive or on...

fourth embodiment

[0086]FIG. 7 is a block diagram of the multi-network interface device 200. The embodiment of multi-network interface device 200 illustrated in FIG. 7 is substantially similar to the multi-network interface device 200 illustrated in FIG. 6 except for a dual high frequency AFE 702. The dual high frequency AFE 702 includes two separate inputs configured to independently and simultaneously communicate signals in the high band 306 and through both the telephone line interface 202 and the powerline interface 204.

Abstract

A powerline communications device comprises a powerline communications interface and at least one other communications interface configured to communicate over a computing network. The powerline communications interface is further configured to receive electrical power. The computing network may comprise mediums including powerlines, telephone lines, and / or coaxial cables. In some embodiments, the powerline communications interface may communicate with a network apparatus, such as a personal computer, via an Ethernet interface. The powerline interface, the telephone line interface, and / or the coaxial cable interface may all be associated with the same media access control (MAC) address. The powerline communications device may receive a message via a first medium and repeat the message via a second medium based on a quality of service (QoS) metric. In some embodiments, the powerline communications device may communicate using multiple frequency bands.
